Mr. Carroll's broken rib pierced through his right lung causing air to enter the intrapleural space. What will happen to his lung, intrapleural pressure, and intrapulmonary pressure?
What will be an ideal response?
Air in the intrapleural space is known as pneumothorax. If intrapleural pressure increases to a level at or above atmospheric pressure, the intrapleural pressure can no longer exert a suction effect that prevents the lungs from collapsing. The added intrapleural pressure enhances the lungs' elastic recoil and the lungs collapse.
